Website: Experimental Probability

Explain how you would use this site:

This website displays a great demonstration of experimental probability. I would use this website to facilitate the entire class in an interactive demonstration. I would first discuss with the class the theoretical probability of each scenario, then have the students use the website to calculate the experimental probability.

For example: User the spinner application the theoretical probability will depend on the number of colors displayed and how many times. Let's say the spinner has 4 colors (all different). What would be the theoretical probability that the spinner would land on red = 1/4. Therefore we would experiment by spinning it 4 times to see how many times it hits red.

With each scenario I would have students complete more trials. I would continually be asking questions to help students reach a conclusion that the more trials we have in experimental probability the closer we get to the theoretical probability.

I would then try a spinner that contained two colors that were the same. for example, blue, red, yellow, green ,red, and yellow. Next i would have students calculate the theoretical probability of getting yellow. Then we would experiment. This would be a great activity to help reach the adaptive dimension to challenge higher level students.

Explain how your studenst would benefit from this site:
The Site collects the data as the students complete the experimental probability therefore having on hand the complete collection of data for analysis to be used. Students will be visually stimulated by the use of the spinners. This could also be a an interactive site used on a SMARTBOARD. That could be used as a class.
